20398387 Volvo Lamp Housing | Heavy-Duty Lighting Precision Solution
20398387 Volvo Lamp Housing
Designed for "precision light alignment in heavy-duty applications", the 20398387 Volvo Lamp Housing (20398387/20393389/20398389/1062163/8191561/3175884) employs impact-modified polyamide with UV-stabilized coating for VOLVO FM7/FM12/FM10 series trucks. The injection-molded housing features integrated heat dissipation channels that reduce thermal stress by 35% compared to conventional designs. Precisely calibrated mounting tabs ensure ±0.5mm positional accuracy across production batches, compatible with 1998-2010 model years. The asymmetric airflow pattern prevents dust accumulation while maintaining optimal lamp cooling efficiency through directional ventilation ports.
Vehicle Integration
Engineered to resolve "vibration-induced light misalignment", the housing system utilizes six-stage compression molding that achieves OEM-grade dimensional stability. The interlocking edge design creates seamless transitions between cab contours and lighting modules, distributing mechanical stress through 20398387's patented rib reinforcement pattern. Chemical-resistant polymer formulation withstands prolonged exposure to road salts and hydraulic fluids, while the 3.2mm wall thickness balances impact resistance with weight optimization. Color-coded alignment markers and pre-installed M6 threaded inserts enable tool-free maintenance access, compatible with both halogen and LED lighting systems through adjustable reflector mounts.
Material Engineering
| Component | Material | Certification |
|---|---|---|
| Main Housing | PA6-GF30 | ISO 527 |
| Seal | EPDM Rubber | DIN 53504 |
The modular construction allows individual replacement of lens retention clips without full housing disassembly, featuring eight service access points per 20398387 unit. The textured surface finish reduces visible scratches by 50% compared to smooth surfaces, while maintaining 92% light transmission efficiency. All electrical connectors utilize gold-plated terminals with IP67-rated moisture protection, and the hybrid snap-fit/adhesive bonding system ensures permanent seal integrity across -40°C to 130°C temperature extremes. The aerodynamic shape reduces wind noise by 18dB at highway speeds through computational fluid dynamics-optimized contours.
